Why it’s better to be safe rather than sorry! Chemical sunscreens are coming under a lot more questioning for good reason –

Chemicals long used in sunblock are under new scrutiny — and may signal it’s time to start reaching for alternatives.

Some of these chemicals enter the bloodstream at a rate that should require additional safety data, according to a preliminary study published earlier this month in the Journal of the American Medical Association.

The four chemicals — avobenzone, oxybenzone, ecamsule and octocrylene — are among the 12 ingredients that the FDA recently flagged in its efforts to update sunscreen regulations. The administration has proposed new rules that would encourage manufacturers to research these chemicals before the government deems them “generally regarded as safe and effective.”

Mineral sunscreens, as opposed to chemical sunscreens, are a better bet, says Upper East Side dermatologist Michele Green. They contain zinc oxide and titanium dioxide — which the FDA has deemed generally safe and effective.

They physically block both UVA rays (those that can cause premature aging) and UVB rays (the ones responsible for burns), providing a shield on the surface of skin, instead of absorbing the sun’s rays as chemical sunscreens do.
